Abstract

One of the terminals constituting a computer system is uniquely selected according to a predetermined algorithm every update of shared data stored in the terminals and broadcasts the update information to the other terminals. Information on the member data on the members in a group is handled as the shared data. An identification number is given to the update information on the shared data. In broadcasting, the identification number along with the update information is transmitted and the terminals manage the identificatio n number as the shared data.
